You may think that you can't do anything because you are not in the top yet, but that's not right. You can and everyone can. We have so many curators, a project to curate and many ideas to do something even without being there like you said. Not all people here are for rewards, they need attention, they need support, they need guidelines. So, you can do what's on your hands and if everyone at least do something small it will be good. We just need more people who work for the favor of the community and everything will be ok. For example setting a goal to comment a few times a day may help you find those people who will be excited about the community even more, the more we have of such people, the better everything here will be.
